その後、分子系統学的解析により、Brauniellula 属のタイプ種であるB. albipes (Zeller) A. H. Smith and Sing. がクギタケ属の種類であることが確定した[15][18]ため、Brauniellula 属とクギタケ属とはシノニムの関係となった。国際藻類・菌類・植物命名規約に規定された命名の優先権からすれば、Brauniellula 属(設立は1958年)がクギタケ属(独立した属としての設立は1968年)に優先し、後者の属名は無効名となるが、クギタケ属を命名規約上の保留名として残す提案[4]がなされ、B. albipesには、クギタケ属の所属種としてChroogomphus albipesの学名が当てられることになった。これによって、従来からクギタケ属に置かれていた多数の種の学名もそのまま維持され、クギタケ属の存続が容認された。
従来は、クギタケ節 Section Gomphus およびフサクギタケ節 Section Floccigomphus (Imai) O. K. Miller(かさの表皮はゼラチン化しない。かさは乾いてもほとんど光沢を生じることはなく、湿った時にのみ、わずかに粘性をあらわすにとどまる)の二つの節に分けられていた[13]が、分子系統学的解析によれば、これら二つの節はともに単系統ではないとの見解が示されている[15]。
